Problem with inlined unsupported image types

[Knut Anders Hatlen <kahatlen@gmail.com>]

Hi,

I have an Emacs that's compiled with --without-gif (it's the Emacs that
comes with Solaris). If an HTML mail contains a remote gif image and I
press W D W, an icon that illustrates a broken image is shown (well,
actually, it illustrates a broken lock, but that's close enough, I
suppose...). That's fine, of course.

But if the HTML mail contains an inlined gif image, I get the error
"Invalid image type `gif'", and the mail is shown in raw format. Here's
the backtrace:

Debugger entered--Lisp error: (error "Invalid image type `gif'")
  signal(error ("Invalid image type `gif'"))
  error("Invalid image type `%s'" gif)
  image-type("GIF89ar...." nil t)
  create-image("GIF89ar...." nil t)
  apply(create-image "GIF89ar...." nil t nil)
  gnus-create-image("GIF89ar...." nil t)
  gnus-html-wash-images()
  gnus-html-wash-tags()
  gnus-article-html((#<buffer  *mm*<4>> ("text/html" (charset . "ISO-8859-1")) 7bit nil nil nil nil nil))

I suppose we should somehow detect if the image type is supported and
make the same thing happen with inlined images as with remote images?
